My first experience with hearing something different on the radio that caught my interest was as a kid in the 70's when I fiddled with the IF cans in a portable transistor radio and heard the Voice of Moscow, Autralian Broadcasting Company, and Voice of America. 

I was first licensed in 1991 as a Tech, and worked my way up to Extra over the years. I've been mostly out of radio the last several years- just seem to have gotten too busy- but now I'm able to spend more time at it. At the moment I'm working on setting up a decent antenna system that will allow operation on all bands 80m through 440, with beams on 6m, 2, and 440,  and a GAP Challenger for 80m through 10m.

I'm mostly active on D-STAR these days.

I also operate a Broadcastify.com feed that streams the D-STAR traffic from two local D-STAR repeaters here in Livingston county, Michigan. (Listen>Michigan>Livingston County>Livingston County D-STAR Repeaters). Both repeaters are connected to various reflectors (W8LIV-B/C connects to REF024C, K8LCD-B/C is connected to many, including REF004B, REF014C, REF30C, REF001C, and others). 

The monitoring system also includes two Digital Voice Access Points (DVAPs), and a DV-Mega. These DVAP/DVMega boards are each connected to a Raspberry Pi single board microcomputer. The Raspberry Pis are running the Maryland D-Star image, which allows setting each DVAP/DVMega with automatic schedules, so that worldwide nets and other traffic can be served to the stream without operator intervention. Each DVAP/DVMega is operating on a separate simplex frequency, effectively operating as simplex repeaters, allowing local D-Star radios access to the reflectors via RF.

The monitoring radio is an Icom ID-880H scanning the above repeater frequencies, DVAP/DV-Mega frequencies, and local D-Star simplex frequencies.These DVAP/DVMega access points identify on the feed as N8QLT-A, N8QLT-B, and N8QLT-C, which connect on their schedules to various reflectors (REF, XRF and DCS) to feed weekly nets.

Weekly D-Star net schedules can be found at http://dstarinfo.com/nets.aspx

The feed is also streamed from a Raspberry Pi 3 connected to the audio of the Icom ID-880H. The Pi 3 is running Darkice using this configuration: https://wiki.radioreference.com/index.php/Raspberry_Pi_Broadcastify_Build

Other than D-Star on VHF/UHF and now HF with a new IC-7100, I've also had some fun on meteor scatter, and played with PropNetPSK many years ago. Once I have more time to play, I plan to resurrect a system for doing PropNet PSK, and I'll be rebuilding a Drake TR-4C and AC-4 power supply one of these days (turned it on one day and smoked a cap in the TR-4c).
